City officials and representatives from Santa Fe Spring will hold an open house from 3 to 8 p.m. Aug. 31 at La Mirada Activity Center, 13810 La Mirada Blvd., to provide an update on the Valley View Avenue grade separation project.

Business owners and tenants can attend from 3 to 5 p.m.; residential owners and tenants can attend from 6 to 8 p.m.

The grade separation project is a joint effort between the two cities and will involve the construction of an underpass at Valley View Avenue and Stage Road. Upon completion of the project, traffic on Valley View will travel underneath the BNSF railroad tracks.

Officials say the project will reduce traffic delays, noise and emissions from idling vehicles, and improve safety for rail passengers, motorists and pedestrians.

City staff and project personnel will be available to review the project status and construction schedule.
